Frequently Asked Questions

Is 650W enough for my gaming PC?

The CX650 delivers its full 650W as continuous power, which suits most single-GPU mid-range builds. Check your specific GPU and CPU maker's recommended PSU wattage before buying, since high-end cards can require more headroom.

Is the CORSAIR CX650 modular?

No. This is a non-modular unit, so all cables are permanently attached to the power supply. Plan on routing and tucking away any connectors your build does not use.

How loud is the CX650 under load?

It uses a 120mm thermally controlled fan that only spins at high speed when the unit is under heavy stress, slowing down for quieter operation at lower loads. Everyday desktop and light gaming use keeps it in the quiet range.

Will the CX650 fit in a small case?

The casing is 125mm long, which CORSAIR states fits easily in almost all modern PC cases. Confirm your case's ATX PSU clearance if you are building in a compact chassis, since non-modular cables need extra room.

What warranty does the CORSAIR CX650 come with?

CORSAIR lists a three-year warranty with support from its global technical team. Check the product listing for current warranty terms in your region before purchasing.
